Bluetooth is a proprietary open wireless technology standard for exchanging data over short distances (using short-wavelength radio transmissions in the ISM band from 2400–2480 MHz) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security.

Size of the display for this product, measured diagonally, usually in inches.
10.16 cm (4")
The number of distinct pixels in each dimension that can be displayed. It is usually quoted as width × height, with the units in pixels: for example, "1024 × 768" means the width is 1024 pixels and the height is 768 pixels. The higher the number of pixels, the sharper the image.
400 x 800 pixels
A screen of a laptop, smartphone, etc., that responds to touch so you can control the interface using your fingers.
The device e.g. smartphone, tablet uses gravity to sense whether it should be displaying in portrait or landscape mode.
Display number of colours
Touch screen type
There are a variety of touchscreen technologies that have different methods of sensing touch, including resistive and capacitive.
The speed that the microprocessor executes each instruction or each vibration of the clock. The CPU requires a fixed number of clock ticks, or cycles, to execute each instruction. The faster the clocks rate, the faster the CPU, or the faster it can execute instructions. Clock Speeds are usually determined in MHz, 1 MHz representing 1 million cycles per second, or in GHz, 1 GHz representing 1 thousand million cycles per second. The higher the CPU speed, the better a computer will perform.
A family of processors is a group of processors produced by one company over a short period of time e.g. Intel Pentium processors.
The model number for the processor in a computer.
Internal storage capacity
Compatible memory cards
Maximum memory card size
Main camera resolution (numeric)
The level of detail in the images that can be captured the main camera. The higher the resolution, the more detailed (and sharper) the image.
The product has an internal flash. A flash produces a brief very bright light, used for taking photographs in poor light.
Indicates the digital zoom capacity, the number of times that the picture is enlarged thanks to digital technology.
Amount of data measured in pixels that the product captures to form the image
2592 x 1944 pixels
Second camera resolution
Third generation of mobile telecommunications technology, 3G finds application in wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV.
SIM card capability
The type of wireless local area network (LAN). It can be ad-hoc, where units in a network communicate peer-to-peer, or Infrastructure, where units communicate with each other via an access point A LAN interconnects computers in a small area e.g. home, school or office.

Bluetooth is a low-power radio technology developed to replace the cables and wires currently used to link or connect electronic devices such as personal computers, printers, and a wide variety of handheld devices including mobile phones. Because it uses radio-wave connectivity, a Bluetooth-enabled device has a constant, established connection to whatever browser it uses. This saves the user the trouble of logging on to check for emails or news updates, for example.
2G bands (primary SIM)
850, 900, 1800, 1900 MHz
3G bands supported
900, 2100 MHz
Ports & interfaces
Universal Serial Bus (USB) is an industry standard developed in the mid-1990s that defines the interface used for connection, communication and power supply between computers and electronic devices. Every new version - for example 1.1, 2.0, 3.0 - is much faster than the previous one.
USB 2.0 ports quantity
Number of USB 2.0 ports (connecting interfaces) in the device. USB 2.0 was released in April 2000 (now called "Hi-Speed"), adding higher maximum signaling rate of 480 Mbit/s (effective throughput up to 35 MB/s or 280 Mbit/s), USB 2.0 ports are usually black.
Colour of product
The colour e.g. red, blue, green, black, white.
Operating system installed
Type of operating system on a device e.g. IOS on Apple devices, Android for mobile devices.
Operating system version
The version of the operating system used e.g. 4.1, 4.2 for Android.
Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. The system provides critical capabilities to military, civil and commercial users around the world. It is maintained by the United States government and is freely accessible to anyone with a GPS receiver.
Electronic instrument used for navigation that shows directions in a frame of reference (north, south, east, west) that is stationary relative to the surface of the earth.
Frequency-modulated (FM) radio gives the clearest reception of any radio band. When used with a headset, it delivers stereo-like sound.
Radio Data System (RDS)
RDS (Radio Data System) means that information such as time, station identification and programme information can be displayed by the device.
